dpkg --get-selections provides a list of all packages that are

error.
But this list does not contain any information about the dependencies
among the packages.
The list is created from /var/lib/dpkg/status by each package management
tool when needed within their tool.
Is there a program that will analyze a list of packages and arrange
them into a tree, or forest (multiple independent trees)?
aptitude comes close but not the level you expecting. Graphical display
will be nice.
I am curious
as to what is the minimum set of apt-get install terms that are
necessary to reproduce my installation (or any particular
installation).
Second question: The dependency relation forms a network on the set of
packages. Is this network a multi-tree, or are there loops within this
network?
Some developer say loop-less is needed and other developer to remove
loops. But some developer insist to keep it. You can find repeated
posting in debian-devel on this subject.
